PART OF THE PERMANENT YWAY OF RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 349,913, dated September 2B, 1886.

Application filed June 16, 1886.

To all whom, it may concern:

Be it known that we, JAMES HONIBALL TozER and WILLIAM ToZER, both of London, England, have invented certain new and useful Improvements in Parts of the Permanent Vay of Railways, of which the following is a specication.

Our invention relates to the permanent way of railways, and has reference more especially to the securing of the chairs to the sleepers,and particularly to sleepers made of wrought iron or steel.

Our invention provides chairs with two or other number of projections or parts, which, by a turning movement, when the chair has been placed upon the sleeper at an angle to the normal position, become tightly jammed or wedged with corresponding parts of the sleeper, whereby a perfectly rm and secure fastening of the chair to the sleeper is formed, no additional fastening being necessary.

The manner in which we prefer to carry out our invention is as follows: We make the chair with wedge-shaped or beveled ends, and with a pin forming a pivot, upon which the chair can be turned, and we construct the sleeper with lips or lugs to receive the beveled ends of the chair, and with a hole to receive the pin. Thelips or lugs can be pressed out of the solid metal of the sleeper. In order to iix the chair, it is rst placed upon the sleeper at an angle to the normal position, and with the pin in the hole. The chair is then turned upon the pin, so as to bring the beveled ends under the lips or lugs, with which they therefore become tightly jammed. If preferred, the bevels may be on the lips, instead of upon the chair ends, or both may be beveled.

The annexed drawings illustrate our invention. Y-

Figure l is a section through the center of the chair; Fig. 2, an end elevation, and Fig. 3 a plan showing a sleeper, chair, and rail, the chair being of the form we prefer to adopt when made of wrought-iron or wrought-steel,and to receive a flat-bottomed rail. Fig. 4 is a sec` tion similar to Fig. l, and showing a modifica tion. Figs. 5, 6, and 7 are views answering to Figs. 1,2, and 3, and showing our invention as adapted to a doubleheaded or H rail.

Referring iirst to Figs. 1, 2, and 3, a is the Serial No. 205,372. (No model.)

sleeper, which, as shown, is a metal sleeper of inverted -trough section. Z) is the chair, and c the rail.

d d are two lips or lugs pressed out of the solid metal of the sleeper, and at e is a holein the sleeper.

`fis a pin on the chair to enter the hole e. The ends of the chair are beveled, as is best seen in Fig. 2, and the bevel is preferably double-that is to say, the first or outer portion, g, is beveled to a certain degree-say one in ten-while the second or inner portion, g', is beveled in a less degreesay one in thirtybut, if desired, the bevel may be the same throughout.

Vhen it is required to iiX the chair, it is first placed upon the sleeper at an angle to its normal position, (see the dotted lines in Fig. 3,) and With the pinj' in the hole e. The chair is then turned upon thepin, so as to bring the beveled endsgg under the lips or lugs d d, wit-h Which they become tightlyjammed. The beveled chair ends gg and the lips d d should be so arranged relatively to each other that considerable force is required to drive the beveled ends home. The lips d d may be beveled as well as or instead of the chair ends g g. lt is preferred, but not essential, to bevel both the lips and the chairs.

h represents a metallic key-fastening for tixing the rail in the chair. Ifwooden keys are to be used for this purpose,the chair-j aw should be of the form represented in Fig. 4, or approximately so. If the chair be made of castiron, instead of wrought iron or steel, it will be of similar form, but of fuller proportions throughout.

Figs. 5, 6, and 7 illustrate our invention as adapted to a double-headed or bull ra-il. By preference we make the chair of cast-iron, of the form shown. It is secured to the sleeper in the same manner as that shown in Figs. 1, 2, and 3.

The same letters of reference indicate corresponding parts.

i is a pad or layer of felt or other suitable material between the chair and the sleeper to lessen jar or concussion. The use of this pad is optional. The pin f is not necessarily placed in the middle of the chair, as shown. This vertical pin f on the under side of the IOO gaged with corresponding fastening projections on a sleeper, substantially as set forth.

2. The combination, With a sleeper having opposite projections,v of `a chair constructed with corresponding inclines or beveled provisions on its opposite sides or ends, adaptedto be engaged With the projections on the sleeper by a twisting movementof the chai-r relatively to the sleeper, substantially as set forth.

3. The combination7 with a sleeper having opposite overhanging projections7 .of a chair having corresponding inclinesladaptcd' to enter beneath said projections laterally by a twisting movement of the chair and a swiveled or pivotalfconnection between said chair and sleeper, substantially as set forth.

4C. The combinatiomwith a Qsleeperand chair having reciprocal locking pro-visions adapted to be engaged by aitwisti'ng movement of said chair, of a pivot-pinoli one of said parts and a socket thereforiinthe other, substantially as set forth.
